[Bug 1168526] Re: race condition causing lxc to not detect container init process exit

[Pavel Bennett]

I can't try Saucy right now, but the repro instructions with kernel
versions are in the original post and in #2.

We've tried node v0.11.2 as well on Raring and got the repro.

Repro summary:

Install any of the above kernels, such as the one with the Raring installer, then install lxc from apt.
Get node v0.11.0 - v0.11.2 or try any other recent version if that's easier, just not below v0.10.
lxc init process is "/usr/local/bin/node /boot/mio-init.js" which contains only "process.exit(0);" and try running 100 of these, whether in parallel or one at a time. Continue until lxc-start doesn't exit. Run "ps faux" and look for zombie children of lxc-start.

Let me know if that works for you :)
